My new hotwire cutter turned up today and what a shiny new toy it is! It's mains powered unlike the GW one, so no more dead batteries or wires that arn't hot enough. So, with my new cutter in one hand and a camera in the other (not literally!), I cracked on with trench system.
I only managed to calve one trench piece as filming took quite a while, but overall I'm pretty happy with it. Here are the pics :
I'm going to work on the rest of the pieces over the weekend as I've got a couple of busy days ahead of me.
